Before crushing, it needs to be cleaned first, and the ingredients should be mixed according to the formula ratio. Crushed into powder above 40 mesh, and then add standard flour, additives and other mixing, so that the mixture is uniform, and the coefficient of variation is not more than 10%. Normally, the raw materials crushed by feed processing machinery generally have a moisture content of about 13%.
The advantage of this is not only to make the moisture content of the feed particles uniform, but also to achieve to meet the softening requirements. After the steam is added, the temperature of the material is rapidly increased, prolonging the time of material pasting, the starch is fully pasted, and the working temperature of the pressure mold is reduced accordingly, improving the service life of the pressure mold of the feed processing machinery.
